cairo 1.0 release requirements
==============================
Implementation work
-------------------
I1. Fix clipping to be sane
Dificulty: moderate
Status: otalyor is working on this.
I2. Real PostScript/PDF fallbacks (cairo_meta_surface_t)
Difficulty: hard
Status: krh has committed cairo_meta_surface_t and a preliminary
version of cairo_ps_surface_t that uses it.
✓I3. Add support for sub-pixel (ARGB) rendering of text.
Status: Done.
I4. Fix the cache lock deadlocking problems.
Difficulty: Hard
Status: The cache code was ugly enough that I ended up doing a
major rewrite rather than just reviewing the
locking. The upside is that the rewrite should also
add the missing metrics caches which will fix some
performance problems with text measurement. Almost
done now.
I5. Finish the workaround for Render's overlapping source/dest bug
(Copy the source as needed)
I6. Fix all expected failures (XFAIL) in the test suite. Either
there's a bug that needs to be fixed, or there are illegitimate
tests that should be removed.
API additions (more detail in TODO file)
----------------------------------------
✓A7. cairo_surface_mark_dirty and cairo_surface_flush
Difficulty: trivial to add API, moderate to actually optimize
based on it
Status: cworth has sent an API proposal to the list for
cairo_surface_mark_dirty. Recent discussions suggest
that cairo_surface_flush will need to reset the clip.
✓A12. cairo_xlib_surface_set_drawable
Difficulty: Easy
Status: Done.
Performance work
----------------
P2. Generate better trapezoids to go easier on the rasterizer
Difficulty: moderate to hard
Status: cworth drafted a plan to the list
P3. Glyph measurement needs to be sped up.
Status: Now planned as part of I4 above ("cache lock deadlock")
Things that have been dropped from the 1.0 roadmap
==================================================
A3. Add cairo_begin/end/get_group
Difficulty: easy to hard (depending on how sophisticated an
implementation is acceptable, and whether the
cairo_meta_surface_t mentioned in [I2] is done)
Status: cworth has a posted a preliminary patch, and keithp,
krh, and otaylor answered all the tough questions it
raised. There's not much work left to finish this one.
